| giuseppe@132 | 2 | =========================== |
| giuseppe@132 | 3 | |
| giuseppe@132 | 4 | The definition of each SCC product requires the specification of all the lidar channels needed to calculate it. For example, for a Raman backscatter product it is necessary to speficy which elastic and Raman lidar channels need to be used to compute the particle backscatter profile. |
| giuseppe@132 | 5 | |
| giuseppe@132 | 6 | The list of the channels to be provided depends on the product type and also on the product usecase_. |
| giuseppe@132 | 7 | |
| giuseppe@132 | 8 | .. _usecase: usecases.html |
| giuseppe@132 | 9 | |
| giuseppe@132 | 10 | |
| giuseppe@132 | 11 | In particular, the number and the type of the lidar channels to be linked to a product for a particular usecase is given by the input channels (i.e. the channels you find on the top of each usecase schema) given in the definition of the corresponding usecase. |
| giuseppe@132 | 12 | |
| giuseppe@132 | 13 | For example, from the schema defining the usecase 5 of Raman backscatter product we find that 4 channels need to be linked: |
| giuseppe@132 | 14 | |
| giuseppe@133 | 15 | - 2 elastic channels (one for near range and another for the far range - *elTnr* and *elTfr*) |
| giuseppe@133 | 16 | - 2 Raman channels (again one for near range and one for the far range *vrRN2nr* of *vrRN2fr*). |
| giuseppe@132 | 17 | |
| giuseppe@133 | 18 | Lidar channels are linked to a particular product by using the tab 'Product/channel connections' available in each product settings page (from admin section). To make the link two channel characteristics should be provided: |
| giuseppe@132 | 19 | |
| giuseppe@132 | 20 | - channel ID |
| giuseppe@132 | 21 | - Signal Type |
| giuseppe@132 | 22 | |
| giuseppe@133 | 23 | The channel ID is automatically provided when you click on the small magnifying glass available on the right of channel ID field (tab Product/channel connections) and select the channel you want to use in the pop up list (if the channel ID to be included is already known it is possible to type it directly). |
| giuseppe@132 | 24 | |
| giuseppe@133 | 25 | The signal type should be selected among the available options according to the role of the specific channel in the product calculation. To facilitate the consistency between the definition of signal type and what is required by the selected product usecase, the input channels reported in each usecase schema are named according to the available signal types. |
| giuseppe@133 | 26 | |
| giuseppe@133 | 27 | Coming back to the example of the usecase 5 of Raman backscatter, for the near range and far range elastic channels the signal types *elTnr* and *elTfr* should be used. In the same way for the near range and far range Raman channels the signal types *vrRN2nr* and *vrRN2fr* should be selected. |
| giuseppe@132 | 28 | |
| giuseppe@132 | 29 | .. warning:: |
| giuseppe@133 | 30 | If the definition of the channels in "Product/channel connections" is not consistent with what expected from the specified product usecase, an error reporting inconsistent product definition is reported by ELPP module. |
